lMPRCVEMENT IN SEED-DROPPERS.

Specification forming part of Letters Patent No. 139,565, dated June 3, 1873; application filed May 7, 1873.

To all whom it may concern:

Be it known that I, JOHN M. FONDEN, of Springfield, in the county of Sangamon and in the State of Illinois, have invented certain new and useful Improvements in a Seed- Dropper; and do hereby declare that the'following is a full, clear, a-nd exact description thereof, reference being had to the accompanyin g drawings and to the lettersA of reference marked thereon, making a part of this specication.

lhe nature of my invention consists in the construction and arrangement of a seed-dropper, as will be hereinafter more fully set forth.

In order to enable others skilled inthe art to which my invention appertaius to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure l is a bottom perspective view of my seed-dropper; Fig. 2 is a longitudinal section of the slide; and Fig. 3 is a plan view of a part of the saine.

Arepresents the hopper, and B is the bottom plate of the same, said bottom plate being cut out, as shown in Fig. l, so as to form the ri ght-angle shoulders a a and inclines b b, each one of the latter being between two of G represents the seed-slide, which moves back and forth and is within the hopper, provided with a counter-sunk circular recess for the reception of a circular disk or plate, D. This disk is near the circumference provided with six holes, d d, at equal distances apart, which holes form seed-chambers. The disk D is attached to a central hub, f, which passes down through a hole made for that purpose in the center of the circular recess in the slide C. Upon the lower end of the hub f, below and against the under side of the slide, is attached a triangular piece, E, upon which are formed or attached three arms, h It,

extending fromthe center through and beyond the corners of the triangle. As the slide is Amoved back and forth the projecting ends of the arms h h operate against the shoulders a ct of the bottom plate B and turn the triangle E and with it the disk D, the sides of the tri` angle coming against the inclines b b as stops.

At the completion of each stroke of the slide y u C one of the Seedchambers d in the revolving` disk D comes directly above an aperture, e, in

tating disk D so as to cover that chamber, d, y.

in said disk, which isover the aperture c in the slide. This cut-of is fastened to the slide C by a bolt and nut with an elasticwasher or nut, i, placed on said bolt above the inner end of the cut-off, so as to allow the cut-olf to yield or give for any grain of corn that may project out from the seed-chamber. The rotating disk D may readily be removed and another with larger or smaller seed-chambers substi-` tuted, so as to drop more or less corn at each` stroke, as may be desired.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-. ,i

The seed-slide O, provided with an annular recess, in combination with the perforated and rotating diskD, and the stationary cut-off G, all constructed and operating substantially as 4and for the purposes herein set forth.

In testimony that I claim the foregoing, I have hereunto set my hand this 14th day o April, 1873. l
